So let's look at the history of these places, courtesy of Research and Statistics handy charts. The picture they paint isn't terribly upbeat: yes, these parishes show increases, but only if you look at the past few years. Starting with St. John's: ASA in 2005 was about 45, and ASA in 2015 was just under fifty. What we're seeing here may turn into growth in the long run, but what the chart shows is a marginal parish which had a brush with dissolution. Resurrection is a bit harder to puzzle out because the apparent metamorphosis into a Spanish-language mission isn't reflected anywhere that I can see. But there's that chart again, which shows a parish on the verge of extinction transforming into— well, into a marginal parish with negligible income, for with P&P of under $20K the diocese must surely be providing a lot of support.
The situation at St. Peter's is better-documented, not to say notorious. I don't have numbers from before when the rector and a chunk of the congregation went off tot he Antiochians, but ASA in 2015 was roughly two-thirds the 120 or so who attended on an average Sunday in 2005. In the middle the parish nearly came apart, what with internal strife and then the (probably unrelated) murder of one of the outgoing co-rectors. Again, the message is crisis survived rather than a model of growth, for ASA of around 70 is at the low end of viability, though at least their finances are sound enough. Meanwhile, St. John's Mt. Washington (actually a neighborhood in Baltimore) has abandoned its building in favor of the chapel at a nearby retirement community. This is being spun as a positive thing but ASA in the 30-40 range and P&P of $40K and dropping more or less steadily means a congregation that could no longer afford a building and was lucky to find another home.
Here's the ugly truth in this diocese: attendance has dropped, fairly steadily, over a decade, with attendance in 2015 about 73% of what it was in 2005. That parallels the drop in the national church. I'm not going to go through all 100-odd parishes and missions in the diocese, but I have yet to come upon one which has shown significant growth over the period. Some are stable, other erratic, some show declines; and of course, there are the closures.
